v SPECIFICATION forming part of Letters Patent No. 251,443, datedDecember 27, 1881.

Application filed October 8, 1880. Renewed November 8, 1881. (Model.)

screens or sieves without waste of force or thestoppage of the machine;anditcousistsin the means hereinafter more particularly set forth.

In the accompanying drawing, A is a fanningmill of the usual shape andstructure.

B is the shoe usually forming part of such machine.

0 is a crank-pulley mounted on one end of the fan-shaft, andcommunicating motion to the shoe B through apitman or link, D,elbowlever E, mounted upon a bar or bracket, a, secured to the side ofthe mill, and a link, G, which at one end is connected to shoe B at anysuitable point-prefcrably at the opposite side thereof-and at the otherend to an eye formed in or upon a sieve, H, sliding back and forth uponthe arm F of elbow-lever E. The sleeve and arm fit snugly together, andby preference are made square or otherwise angularin cross-section tosecure steadiness. It may be otherwise formed, if desired.

A pivoted link, I, connects the end of the sliding sleeve H nearest tothe pivot of lever E with the inner limb of a hand-lever, K, ex-

sequent throw (or length of reciprocation) of shoe B. A notched segment,L, Iastened outside of the mill, serves to secure the lever K in anydesired position.

It is obvious that changes of detail may be made without departing fromthe spirit of the invention.

My contrivance permits the alteration or throw to be effected withoutstoppage of the machine.

I claim- 1. The combination of crank-pulley 0, link D, elbow-lever E,sliding sleeve H, link G, and shoeB with mechanism for adjusting thesleeve H from the outside of the machine, substantially as and for thepurpose set forth.

2. The combination of crank-pulley 0, link D, elbow-lever E, slidingsleeve H, suitably connected to shoe B, and adjusting-lever L, looselyconnected to sleeve H, substantially as set forth.
